Couch potato—It may be a good way to relax, but watching too much television could shorten your life. Australian researchers analysed data from an observational study of over 10 000 adults conducted between 1999 and 2000. They found that people who watched an average of six hours of television a day lived 4.8 years less than those who watched no television at all (95% CI 11 days to 10.4 years). On average, every hour of television viewed beyond the age of 25 decreased life expectancy by 21.8 minutes (95% CI 6.3 to 44.7).
